BACKGROUND

The present invention generally deals solid fuel burning conventional fireplaces. Many conventional solid fuel burning fireplaces burn such solid fuels as wood, coal, etc. The solid fuel is placed in a burn chamber and is lit. The fuel burns, heating the surrounding ceramics, which in turn radiate heat along with the direct radiation from the fire to heat the room housing the fireplace.

Many of these fireplaces exhaust the heated air of the surrounding along with the exhaust of the fire up through a chimney that leads the heated air outside the home. Unfortunately, these conventional fireplaces are inefficient in that much of the heat escapes with the heated air through the stack, as opposed to not allowing most of the heated air within the surrounding room to escape up the chimney. Further, the exhausts are dirty in that they include many particulates because the temperature of the flame from the burning fuel is insufficient to break down all the particulates.

There exists a need to provide a more energy efficient and cleaner burning solid fuel burning fireplace.

SUMMARY

The present invention provides a more energy efficient and cleaner burning solid fuel burning fireplace.

Various embodiments described herein are drawn to a fire place enhancer for combusting fuel and for placement into a fireplace within a wall of a room, wherein the fireplace has a chimney. The fire place enhancer includes: a main air shield having a main exhaust port, a main access port an air ingestion port and an air supply port; an inner surface disposed with the main air shield so as to provide a combustion area for combusting the fuel, the inner surface having a rear surface and two side surfaces; and a heat manifold disposed above the combustion area, the heat manifold having first end and a second end, the heat manifold being operable to pass gasses from the combustion area to the chimney. The air ingestion port provides ingested air from the room to the heat manifold at the rear surface without entering the combustion area. The heat manifold transfers the ingested air from the rear surface to the main air shield and into the room. The air supply port provides primary air from the room to the combustion area and provides secondary air to the rear surface without entering the combustion area. The rear surface includes an exhaust port operable to provide the secondary air to the combustion area.

DETAILED DESCRIPTION

A fireplace enhancer in accordance with aspects of the present invention provides a secondary burn. This secondary burn has a much higher temperature than a regular burn in a solid fuel burning fireplace and drastically decreases the particulates in the exhausted gases. A fireplace enhancer in accordance with aspects of the present invention also provides the following: 1) control of the primary and secondary air supply; 2) a constricted and partially insulated space to increase the heat for a more efficient burn; 3) a shield to contain the heated air of the surrounding room from traveling through the open fireplace and up the chimney; 4) a surrounding cavity that imports air from the surrounding room, preheats it by conduction from the inner fire walls and circulates it back into the surrounding room via pipes connecting the surrounding cavity to the surrounding room; and 5) a set of pipes that heat air delivered from the surrounding cavity and deliver the air back into the room surrounding the fire place. Since these pipes are located at the top of the fireplace enhancer in accordance with aspects of the present invention, this process adds additional heat to the air passing into the surrounding room and this process cools the exhaust gasses from the fire and reduces the probability of fire.

A fireplace enhancer in accordance with aspects of the present invention includes: a heatilator; a heat manifold; a baffle; a secondary air supply system; an air control shuttle; an air filter/brace; a front air shield; an airwash system; and two front doors.

The heatilater is a hollow steel or cast iron body which surrounds the fire on three sides with openings on the front side of the fireplace to ingest air from the surrounding room. The main function of the heatilator is to preheat the ingested room air and deliver it to heater manifold attached to the back of the heatilator at the upper most location of the wall adjacent to the fire.

The heat manifold may be pipes or tubes that attach from the back of the heatilator to the upper portion of a front air shield. The heat manifold transfers the heat from the exhaust gasses from the fire to the air passing from the heatilator to the front air shield and back into the room where it originated. This super heats the air returning to the room and cools the exhaust gasses from the fire. This action greatly reduces the possibility of a chimney fire. In an example embodiment, the heat manifold may include threaded attachments for hanging a baffle below the heat manifold.

The baffle may be made of steel or ceramic fiber, which hangs below the heat manifold supported by threaded rods attached heat manifold.

In an example embodiment, the secondary air supply system includes rectangular tubes arranged at right angles passing air from the front floor of the fireplace to the back bottom of the fireplace enhancer to an elevation just blow the baffle and discharging through holes at the end of the assembly. The secondary air heated by the conducting tube is united with the hot unburnt gasses of the fire producing a secondary burn of intense heat thereby eliminating harmful particulates.

In an example embodiment, the air control shuttle includes a bar of steel with louvers and a handle that work in conjunction with louvers at the bottom of the front air shield to control the air flow for primary and secondary air.

The air filter/brace delivers primary air through fine slots thereby reducing the possibility sparks being blown back into the surrounding room. This device also acts to hold the secondary air assembly in place.

The front air shield includes a main front shield and an extended air shield including two side wings and a top wing, which are of variable size to adjust the size of the front air shield to fit the front of the fire place. In an example embodiment, the wings are rectangular steel sheets attached to the main front shield with bolts, rivets, welds or other form of attachments. In an example embodiment, the main front air shield is made of steel plate or other heat resistant material and has the following features. Holes may be provided near the top for the heat manifold pipes to exhaust the heated air into the surrounding room. In an example embodiment, two vertical rectangular holes accommodate the air ingestion holes of the heatilator. A hole accommodates the door assembly, which provides view of the fire and access to load fuel. Louver holes near the bottom of the main air shield act in conjunction with the air control shuttle to control the supply of primary and secondary air. A door frame serves as the mounting device far the hinges, two doors and the locking devices for the two doors. The frame also houses the air wash system to keep the windows of the doors clean, and houses the sliding shutoff valves controlling the supply of air for the air wash system.

The two doors include a C-shaped rim bounding a C-shaped plate with C-shaped divider of square stock on the underside of the plate. This square stock divides housing for the rope gasket and the lip to embrace the glass panels of the doors. Handles of the door are secured by threaded nobs mounted at the top of the door plate. The handles are latched by two small narrow notched steel plates attached to the front air shield just above the door frame. A hot air deflector is a rectangular panel mounted at the top of the hot air exit holes near the top of the main air shield. This panel is mounted such that it is parallel to the top of the heat manifold pipes. The deflector is held in place by plates welded to the deflector, which slide several inches down the throat of the heat manifold pipes. This mechanism deflects the very hot air from the heat manifold pipes away from the front of the fireplace to protect a mantle. This unit is only mounted and used if necessary.

Baffle 1102 provides three functions when fuel is combusting in combustion area 410. Firstly, the combustion process generates infrared heat that is emitted omnidrectionally. Baffle 1102 reflects a portion of the omnidirectionally emitted infrared heat back toward combustion area 410 to increase the heat in combustion area 410. The infrared heat reflection increases the temperature in combustion area 410, and thus making the combustion process more efficient and decreasing the overall resulting particulates.

Secondly, baffle 1102 directs the air exiting secondary exiting exhaust ports 606 as indicated by arrow 612 toward the upper portion of combustion area 410. This air mixes with the heated air combusted in the primary burn (the primary air provided to combustion area 410 as discussed above with reference to arrows 614 and 616 in FIG. 6). The air from exhaust ports 606 as directed from baffle is used to provide a secondary burn with the unburnt gasses and particulates mixed in the heated exhaust gasses from the primary burn. This secondary burn provides additional heat and decreases overall resulting particulates.

Thirdly, baffle 1102 insulates heat manifold 602 from the increased heat generated by the secondary burn, thus preventing air that is circulated back into the room through heat manifold 602 from becoming too hot.

In accordance with an aspect of the present invention, a large air shield assembly that includes a main air shield with two side extensions and a top extension that prevent the warm air of a room surrounding a fireplace from escaping through the fireplace and up the chimney. The large air shield assembly provides an additional benefit of radiating heat absorbed from the combustion processes out into the surrounding room environment.

In accordance with another aspect of the present invention, a baffle reflects heat back into the combustion processes thereby making these processes more efficient and producing less harmful particulates.

In accordance with another aspect of the present invention, a secondary air supply system in conjunction with the baffle causes the heated secondary air to unite with the rising unburnt gasses from the primary combustion to produce an intensely hot secondary burn that eliminates even more harmful particulates.

In accordance with another aspect of the present invention, an air control system limits and adjusts the amount of air provided to the primary and secondary combustion processes.

In accordance with another aspect of the present invention, a large viewable port is provided to observe combustion and give access for attending fuel. This viewable port has doors with large glass shields that provide greater radiation of heat into the surrounding room.

In accordance with another aspect of the present invention, a heat manifold of secured pipes located at the top of the fireplace enhancer. The extremely hot exhaust gasses escaping from the combustion processes the heat manifold, pass around these pipes thus transferring heat through the pipes to further heat the air passing through the pipes and into the surrounding room. This process cools the hot exhaust gasses passing around the pipes and up the chimney thus reducing the chances of chimney fires. The arrangement of the heating components and the double heating of the circulating room air yield an efficient heating system without any mechanical system.

In accordance with another aspect of the present invention, a heatilator surrounds the combustion processes and extracts a great deal of the generated heat and transfers this heat to the ingested air from the surrounding room. This heated air is exhausted into a heat manifold and out into the surrounding room.
